Application October 4,

2 Claims.

This invention relates to containers for condensed, evaporated or prepared milk and other liquids of substantially equal consistency, and has for the primary object the provision of a device of this character, whereby liquid may be marketed and stored to maintain the liquid free of foreign matter and evaporation and after reaching the consumer may be easily dispensed in desired amounts while the remaining liquid therein will be kept in a sanitary condition until needed by the consumer.

With these and other objects in View, the invention consists in certain other novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which- Figure 1 is a side elevation illustrating a container constructed in accordance with my invention.

Figure 2 is a top plan view illustrating the same.

Figure 3 is a. sectional view taken on line 33 V of Figure 2.

Figure 4 is a fragmentary vertical sectional view illustrating a modification of the invention.

Referring in detail to the drawing, the numeral 5 indicates a container of any desired capacity, the top wall 6 thereof being formed integrally with a discharge spout 1 preferably in the form of a tube, the free end of which is externally screw threaded, as shown at 8.

A valve seat 9 is formed in the spout 1 where the latter joints the top wall 6 of the container 5 and is engaged by a ball type valve I!) connected to one end of a coil spring ll confined in the spout, the other end of the spring being secured on the spout, as shown at l2. The spring l acts to seat the ball valve to close the interior of the container to the spout and thereby maintain the contents free of foreign matter and evaporation.

A cap I3 is threaded on the spout I and carries a stem or rod [4 located centrally of the spout and has the free end thereof concaved to engage the ball valve ID to retain the latter in tight engagement with the seat 9 when the cap I3 is threaded fully onto the spout. Through the use of the cap I3 and the stem l4 no possibility of the ball valve l disengaging the seat 9 will be had so that the container may be shipped filled with liquid without danger of waste or leakage. When desiring to obtain the contents of the container the cap I3 is removed along with the stem 1938, Serial No. 233,297

M so that when pressure is applied on the container the contents will force the valve l0 away from the seat and allow the contents to escape from the container by way of the spout 7.

The spout 1 adjacent its connection with the container is provided with an opening I normally closed by a sleeve I6 rotatably mounted on the spout. The sleeve It has an opening l! which when brought in registration with the opening l5 will permit the pouring of hot Water into the spout l for the purpose of cleaning or sterilizing the same prior to the dispensing of the contents. The ball valve In being in a seated position at the time of placing hot water in the spout prevents the water from reaching the interior of the container and mixing with the contents.

The top Wall 6 of the container may be provided with indentations Hi to be punched out when desiring to vent the container so that the entire contents may be emptied therefrom.

Referring to my modified form of invention as shown in Figure 4, the spout 7 has threaded thereon a cap l9 having an opening; The discharge end of the spout l in this instance is equipped with an end wall 2| having an opening 22 and also an opening 23 through which the stem l4 passes with a comparatively tight fit. In this form of my invention it is not necessary to entirely remove the cap 19 in order to dispense the contents of the container. To obtain the contents from the container, the cap 59 is partially unscrewed so as to bring the opening 20 in registration with the opening 22 and allowing the stem I4 to move away from the ball valve so that when pressure is placed on the container the contents will discharge by unseating the valve and flowing through the openings 22 and 20. In the use of the modified form of the invention it is not necessary to employ the opening IS in the spout and the sleeve l6.

It is believed that the foregoing description, when taken in connection with the drawing, will fully set forth the construction and advantages of this invention to those skilled in the art to which such device relates so that further detailed description will not be required.

What I claim is:

1. A container comprising a container portion, a spout integral with said container portion, a valve seat in said spout, a spring influenced'valve element engageable with the seat, a closure cap threaded on the spout and having an opening, an end wall for said spout and having an opening adapted to be aligned with the opening of the cap to permit discharge of contents from the container portion by way of the spout when pressure is applied to the container portion for the unseating of the valve element, and. a stem carried by the cap and extending through the end wall to engage the valve element to retain the latter in engagement with the seat until the opening of the cap and the end wall have been aligned through the partial unscrewing of the cap from the spout.

2. A container comprising a container portion, a tubular spout integral with said container, a valve seat located in the spout, a ball valve to engage with said seat, a coiled spring having one end secured on an interior wall of the spout and the other end secured on the ball valve to normally position the latter in engagement with the seat, a cap threaded on said spout, and a stem carried by said cap and extending through the coiled spring to engage the ball valve for forcing the latter into engagement with the seat and adapted to permit the ball valve to move off of the seat when said cap has been partially unthreaded from the spout and pressure applied to said container portion.
